The aim of this paper is to provide non-specialist readers with an introduction to some current controversies surrounding the application of evolutionary theory to human behaviour at the intersection of biology, psychology and anthropology. We review the three major contemporary sub-fields; namely Human Behavioural Ecology, Evolutionary Psychology and(More)
In 1948, Angus J. Bateman reported a stronger relationship between mating and reproductive success in male fruit flies compared with females, and concluded that selection should universally favour 'an undiscriminating eagerness in the males and a discriminating passivity in the females' to obtain mates. The conventional view of promiscuous, undiscriminating(More)
The vibrancy of the field of evolution and human behaviour belies the fact that the majority of social scientists are deeply unhappy with evolutionary accounts of human behaviour. In part, this reflects a problem within evolutionary biology: neo-Darwinism fails to recognize a fundamental cause of evolutionary change, “niche construction”, by which organisms(More)
Evolutionary Psychology (EP) views the human mind as organized into many modules, each underpinned by psychological adaptations designed to solve problems faced by our Pleistocene ancestors. We argue that the key tenets of the established EP paradigm require modification in the light of recent findings from a number of disciplines, including human genetics,(More)
High levels of prolactin have been found to correlate with the expression of paternal care in a variety of taxa. However, in mammals, there is little experimental evidence that prolactin is causally involved in the stimulation or maintenance of paternal care. Here, we suppressed prolactin production in paternally experienced common marmoset fathers in their(More)
During adolescence, rats gain independence from their mothers and disperse from the natal burrow, with males typically dispersing further than females. We predicted that, if dispersal patterns are associated with responsiveness to novelty, exploratory behavior in novel environments would increase across adolescence, and males would explore more than(More)
Trivers and Willard hypothesized that vertebrates adaptively vary the sex ratio of their offspring in response to the mother's physical condition [Trivers, R. L. & Willard, D. (1973) Science 179, 90-92]. This hypothesis has produced considerable debate within evolutionary biology. Here we use meta-analysis techniques to evaluate claims that nonhuman primate(More)
